Solutions to several VTK compilation errors (vtk5.8 + VS2010)

There are several common errors that can occur during the compilation of a VTK project. The solutions are as follows:
error 1:
fatal error C1189: #error : This file requires _WIN32_WINNT to be #defined at least to 0x0403
cause:
The minimum version of the system set for version migration is too low
Visual C++ 2010 no longer supports targeting Windows 95, Windows 98, Windows ME, or Windows NT. If your WINVER or _WIN32_WINNT macros are assigned to one of these versions of Windows, you must modify the macros. When you upgrade a project that was created by using an earlier version of Visual C++, You may see compilation errors related to the WINVER or _WIN32_WINNT macros if they are assigned to a version of Windows that is no longer supported (From MSDN)
The immediate cause – there are three lines of code in atlcore.h:
#if _WIN32_WINNT < 0x0403
#error This file requires _WIN32_WINNT to be #defined at least to 0x0403. Value 0x0501 or higher is recommended.
#endif
> bbb>
All in VTK directory stdafx. H file reference to modify WINVER, http://msdn.microsoft.com/en-us/library/aa383745.aspx _WIN32_WINNT, _WIN32_WINDOWS and _WIN32_IE definition, for example: # define WINVER 0 x0501
 


error 2:
error C2371: ‘char16_t’ : redefinition
:
In VTK project files are generated in the process of choosing the Matlab support (tex-mex), and adopted the VS2010 and above programming environment (http://connect.microsoft.com/VisualStudio/feedback/details/498952/vs2010-iostream-is-incompatible-with-matlab-matrix-h) :
I looked at the source code for matrix.h < core/matlab/include/matrix.h>
It has a definition for char16_t
typedef char16_t char16_t;” . Also the C++ header “Microsoft Visual Studio 10.0\VC\ Include \ YVALS. H “Also defines the same identifier(CHAR16_T). Because of these two definitions we get the redefinition error when matrix iostream.h(it internally includes yvals.h) are included in some cpp file.
Declaration of char16_t in the yvals.h is newly introduced in dev10 and was not there in VS2008. Therefore you are getting this redefinition error now on VS 2010(Dev10).

> solution 1 (without follow-up test) : BBB>
//added by John for solving conflict with VS2010
#if (_MSC_VER) < 1600 //VS2010
# ifndef __STDC_UTF_16__
# ifndef CHAR16_T
# if defined(_WIN32) & & defined(_MSC_VER)
# define CHAR16_T wchar_t
# else
# define CHAR16_T UINT16_T
# endif
typedef CHAR16_T char16_t;
# endif
#endif
#else
#include < yvals.h>
#endif//VS2010
> solution 2 (without follow-up test) : BBB>
Rename all char16_t in matrix.h
 
error 3:
LNK4199: /DELAYLOAD:vtkIO.dll ignored; no imports found from vtkIO.dll
cause:
DelayLoad (selected from the in-depth analysis DelayLoad “http://blog.csdn.net/panda1987/article/details/5936770).
As we know, there are two basic methods of DLL loading: implicit loading and explicit loading. Implicit loading is the method introduced in the previous article, where the input table of a PE loads the DLL into the memory space before entering the entry function. Explicit loading uses methods like LoadLibrary and GetProAddress to load the DLL into the process space when needed. Both of these methods are the ones we use most often. So what is delay load?
A DLL designated as Delay Load will not actually load the process space until it is needed, which means that the DLL will not be loaded if no function located in the DLL is called. The loading process is done by LoadLibrary and GetProcAddress, which is, of course, transparent to the programmer.
What are the benefits of this?There is no doubt that the program starts faster, because many DLLs may not be used at startup. Even some DLLs may not be used in the entire life cycle, so with Delay Load, the DLL does not need any memory.
> bbb>
Because for dynamic libraries, the load information is still recorded in the corresponding lib file, so in the properties of the project Linker->; Input-> Additional Depandencies may also have #pragma comment(lib, “vtkio. lib”) at the beginning of the Cpp. If the file is not found by the compile prompt, it is also required in the Linder->; General-> Add the location of the file in the Additional Library Directory.
If someone is the difference between the Lib and Dll unclear, see: http://www.cppblog.com/amazon/archive/2011/01/01/95318.html
